Are there national regulations for standard parking space dimensions?

[ColeFitz]

According to the "Urban Road On-Street Parking Space Setting Standards," the standard dimensions of parking spaces are determined based on vehicle size. Small vehicle parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. The width of a single-lane turning lane should be no less than 3.5 meters, while a double-lane turning lane should be no less than 5 meters. The turning area should accommodate a vehicle's ability to complete a one-time turn. For safety or to accommodate medium and large vehicles, the length is often set to 6 meters or more. Details are as follows: (Length ≤ 6m, width ≤ 1.8m) vehicles: The minimum spacing between vehicles should be no less than 0.5 meters, and the spacing between vehicles and walls or the ends of parking spaces should also be no less than 0.5 meters. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m) vehicles: The spacing between vehicles should be no less than 0.7 meters. Large vehicle parking spaces: Length ranges from 7 to 10 meters, and width is 4 meters, depending on the specific vehicle model. According to the "Architectural Design Standards for Vehicle Garages," the dimensions for small vehicle indoor parking spaces are as follows: The external design dimensions for small vehicles are 4.8m (length) x 1.8m (width) x 2.0m (height). For perpendicular parking, the minimum parking space dimensions should be 5.3m (length) x 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small vehicles and side walls should be 0.6m, and the minimum distance to front and rear walls should be 0.5m. Generally, a parking space covers about 16 square meters. Under building regulations, the legally mandated standard size for indoor parking spaces is 6m x 2.5m, though smaller spaces of 5.5m x 2.5m can also be set up. Mechanical parking spaces must not be smaller than 5.5m in length, 2.2m in width, and 1.8m in height (measured at the outer edge). Therefore, the mechanical width should be deducted, resulting in slightly reduced dimensions, but the height should still not be less than 1.8m. Modern underground garages are large in scale and accommodate numerous parking spaces. To ensure smooth vehicle movement, driveways are planned to be relatively wide. Driveways, as horizontal passages dedicated to parking spaces, account for the majority of the allocated floor area, often occupying 50% or more of the total parking space area. Parking space arrangements can be categorized into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Specifics are as follows: Parallel parking spaces: Standard length is 6 meters, and width is 2.5 meters. Angled parking spaces: The diagonal length should be 6 meters, width 2.8 meters, with a vertical distance of 2.5 meters between the two angled lines. Perpendicular parking spaces: Length should be at least 5 meters, typically set at 6 meters, with a width of 2.5 meters. The optimal standard size is 2.5m x 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces cannot be set up on roads with a width of less than 6 meters. Pedestrian crossings, expressways, and main roads are also prohibited from having parking spaces. Within urban road limits, government authorities may designate parking spaces where pedestrian and vehicle traffic is not obstructed. On-street parking spaces should not interfere with non-motorized vehicle passage or encroach on their space. They should not be placed near intersections, building entrances, or bus stops. Vehicle types and parking durations should be specified via signage, and impacts on vehicle flow should be minimized. Additionally, on-street parking spaces must not be equipped with ground locks to prevent private occupation. Roads prohibiting parking may have barriers, posts, or bollards installed. After removal or cancellation of parking spaces, all related signs, markings, and facilities should be promptly cleared to prevent illegal parking and ensure road safety. Furthermore, on-street parking spaces should not be set up within 200m~300m of off-street public parking lots. Quantitative regulations for on-street parking spaces: The "Urban Road On-Street Parking Space Setting Standards" provides quantitative rules based on road width. For two-way roads, parking spaces can be set on both sides if the actual road width exceeds 12 meters; if between 12m and 8m, only one side is allowed; if below 8m, no parking spaces are permitted. For one-way roads, parking spaces can be set on both sides if the actual width exceeds 9 meters; if between 9m and 6m, only one side is allowed; if below 6m, no parking spaces are permitted. Regarding disabled parking spaces, the standards require that on-street parking spaces should include disabled-accessible spaces, accounting for no less than 2% of the total. If there are over 20 parking spaces, at least one disabled-accessible space should be provided. Parking space marking colors: White: Paid parking spaces; Blue: Free parking spaces; Yellow: Reserved parking spaces; Time-limited parking spaces: Dashed borders with a line width of 10cm; the permitted parking time should be marked inside the border, with numbers 60cm in height. Disabled-accessible parking spaces: Special markings indicate these spaces. Yellow grid lines on either side designate no-parking zones for disabled passenger loading/unloading. Other vehicles must not occupy these spaces. The yellow grid lines should be 120cm wide, with outer lines 20cm thick and inner fill lines 10cm thick at a 45° angle. The outer line length should match the parking space marking length. On-street parking spaces should not be set in the following cases: Fire lanes, road sections with no-parking signs/markings, or construction zones obstructing traffic; Roads designated for disaster relief or emergency evacuation; Sidewalks, unless they do not encroach on tactile paving for the visually impaired; Near building entrances; Intersections, railway crossings, sharp curves, narrow roads under 4m wide, bridges, steep slopes, tunnels, or within 50m of such locations.
